Definitions

  • This invention is directed to a device positioned in a battery well which prevents electric contact when the battery is inserted in the wrong polarity orientation.
  • FIG. 1 is a section through the central axis of a digital watch through the center of the two battery wells to show one embodiment of the no-fault battery insertion device in each of the wells for opposite polarity.
  • FIG. 2 is a perspective view of the device for battery case contact.
  • FIG. 3a is a section through the battery well showing the operation of the device of FIG. 2 with a battery inserted in incorrect orientation.
  • FIG. 3b is a section similar to FIG. 3a through the other battery well with the battery shown as inserted in the incorrect orientation.
  • FIG. 4 is a perspective view of the device for battery button contact.
  • FIG. 1 shows watch module 10 embodying the no-fault battery insertion device of this invention as being positioned in watch case 12.
  • Watch module 10 includes substrate 14 clamped between top spacer 16 and a bottom spacer 18. The manner in which the spacers are clamped on the substrate and the manner in which the substrate is located with respect to the spacers is described in more detail in Roger A. Burke, Bela Somogyi and Rudolf F. Zurcher application Ser. No. 563,927, filed Mar. 31, 1975, for "Electronic Watch Construction.”
  • Substrate 14 is the principal carrier of electronics and electrical interconnections of the electronic watch module.
  • Substrate 14 is preferably a ceramic substrate for its dimensional stability and printed circuitry is printed on both the top and bottom thereof.
  • Contact rings 20 and 22 are printed on the bottom side of substrate 14 above battery wells 34 and 36, respectively. Contact rings 20 and 22 are appropriately connected to the electronic circuitry to power the watch.
  • Batteries 31 and 32 are respectively positioned in battery wells 34 and 36 to provide the power.
  • Battery hatches 46 and 48 are removable from the watch case to permit battery replacement.
  • the batteries are oppositely arranged; that is, battery 31 has its negative contact button 50 directed downwardly while battery 32 has its positive case 52 directed downwardly.
  • These battery terminals are connected together through the metallic battery hatches and the metallic watch case so that batteries 31 and 32 are serially connected.
  • the watch case thus has an intermediate voltage level between the relatively positive case 38 of battery 31 and the relatively negative contact button 40 of battery 32.
  • No-fault battery insertion devices are incorporated so that neither electrical nor mechanical damage can occur if either of batteries 31 or 32 is incorrectly inserted in the wrong polarity position or orientation even if the batteries are forced into the wells and the battery hatch covers are screwed into place against a solid stop.
  • the battery hatch covers themselves may carry compressible contact springs to maintain contact force and accomodate battery size tolerances.
  • FIG. 1 shows the no-fault battery insertion device 54 in battery well 34 for the correct connection of battery 31.
  • Device 54 as seen best in FIG. 2, comprises ring 56 which has spring fingers 58 integrally formed thereof and pressed upward out of the plane thereof. The spring fingers 58 engage against contact ring 20 to urge ring 56 downward against shoulder 60, see FIG. 1, when no battery is inserted in the well.
  • the preferred material of device 54 is metallic spring material or an electrically conductive elastomeric may be substituted.
  • FIG. 1 shows no-fault battery insertion device 70 positioned in battery well 36 to permit the introduction of battery 32 in either insertion position without structural damage and to present electrical connection when the battery is inserted on the wrong electrical polarity position.
  • Device 70 see FIG. 4, has for its electric contact, metallic disc 72 which has four integral spring fingers 74, 76, 78 and 80 pressed upward out of the plane thereof. As seen in FIG. 1, the spring fingers mechanically engage and electrically contact the contact ring 22. Between the spring fingers metallic disc 72 extends outward in its plane to leave flanges 82, 84, 86 and 88.
  • Key ring 90 is an insulator ring which is mounted under flanges 82-88 and is pressed down on shoulder 92 by spring fingers 74-80 in the absence of a battery in battery well 36.
  • negative contact button 40 contacts the underside of metallic disc 72 before the battery case shoulder around the button on the battery contacts angular engagement face 94 on the lower inner surface of key ring 90.
  • electrical continuity is achieved from contact button 40 to disc 72 and thence through its spring fingers 74-80 to contact ring 22.
  • a correctly inserted battery is electrically connected in the well.
  • the no-fault battery insertion structure permits insertion of a battery in either polarity position but only permits electrical contact thereto when the battery is inserted in its proper polarity position.
  • application of voltage of incorrect polarity by wrong battery insertion is eliminated, and at the same time the potential for physical damage from wrong battery insertion is also eliminated.
